FOREST STAND SEGMENTATION USING AIRBORNE LIDAR DATA AND VERY HIGH RESOLUTION MULTISPECTRAL IMAGERY
lidar multispectral imagery fusion feature extraction supervised classification energy minimisation forest stand delineation tree species
2016/7/27
Forest stands are the basic units for forest inventory and mapping. Stands are large forested areas (e.g., ≥ 2 ha) of homogeneous tree species composition. The accurate delineation of forest stands is...
FUSION OF REMOTELY SENSED MULTISPECTRAL IMAGERY AND LIDAR DATA FOR FOREST STRUCTURE ASSESSMENT AT THE TREE LEVEL
Airborne remote sensing Classification Digital photogrammetry Fusion Forestry Lidar Multispectral imagery
2015/12/31
A new feature-level fusion is presented for modelling individual trees by applying watershed segmentation and subsequent classification, using tree heights and tree crown signatures derived from light...

FUSION OF LIDAR DATA AND MULTISPECTRAL IMAGERY FOR EFFECTIVE BUILDING DETECTION BASED ON GRAPH AND CONNECTED COMPONENT ANALYSIS
building detection segmentation LiDAR graph NDVI entropy multispectral imagery
2015/4/1
Building detection in complex scenes is a non-trivial exercise due to building shape variability, irregular terrain, shadows, and occlusion by highly dense vegetation. In this research, we present a g...
EFFECT OF WAVELET COMPRESSION ON THE AUTOMATIC CLASSIFICATION OF URBAN ENVIRONMENTS USING HIGH RESOLUTION MULTISPECTRAL IMAGERY AND LASER SCANNING DATA
Data Compression Wavelets Data fusion Classification
2014/12/31
This paper examines the influence of data fusion and wavelet compression on the automatic classification of urban environments. The principal data used is airborne Daedalus scanner imagery. Laser scan...
